xyExtract Graph Digitizer 2.4
The "xyExtract" software is used for
to extract data from a 2D graph
(orthogonal and nonorthogonal axes)
contained in a graphic file (scanned,
PDF document or in a some file like
GIF, JPEG, etc.).
The graphic file must be saved in a
bitmap file. Then, the "xyExtract"
converts the graph back to xy data
file (up to 1500 points).
If you want, use the "Save Project"
option on the "File" menu, for a
posterior opening of the work. After
each click, use the "Adjustment"
option to move the marked point (pixel
to pixel), if necessary.
Important: The xyExtract is a
easy-to-use software and it guides you
during whole the process for the
points recovery.

DigitizeIt can automatically digitize scanned graphs and output data values.
DigitizeIt is an application that digitizes scanned graphs and charts.
Graphs can be loaded in nearly all common image formats (incl. GIF, TIFF, JPEG, BMP, PNG, PSD, PCX, XBM, XPM, TGA, and PCT) or pasted from the clipboard. Digitizing of line and scatter plots occurs automatically, and manual digitizing via mouse clicks is also possible.
Data values are transformed to a specified axes system and can be saved in ASCII format, ready to use in many other applications e.g. Microcal Origin or Excel. Axes can be linear, logarithmic or reciprocal scale.
Multiple different data sets can be defined and edited. It can handle tilted and distorted graphs, and includes comprehensive online help.

GetData Graph Digitizer lets you digitize graphs and plots
It is often necessary to obtain original (x,y) data from graphs, e.g. from scanned scientific plots, when data values are not available.
GetData Graph Digitizer allows to easily get the numbers in such cases.
With GetData Graph Digitizer, digitizing is a four step process:
- Open a graph
- Set the scale (coordinate system)
- Digitize (automatically or manually)
- Copy data to the clipboard, or export to TXT, XLS, XML, DXF or EPS file.

VKDigitizer
The program performs digitizing graphs (scanned images, etc.). For simplicity and reliability, it supports only manual point selection and rectangular coordinate system, but the image can be rotated to achieve precise alignment of axes.
The acquired data can be formatted according to the needs (number precision, column width, column separator, etc.).

jTechDig
jTechDig is a software tool written in Java for digitizing data from an image of graph or plot. jTechDig can import images from .gif, .bmp, .png, etc. files. After mapping of the coordinates system the data can be digitized manually by clicking the mouse.
The graphs can be magnified and panned for higher accuracy. The captured data can be saved to text file where the data are separated by semi-colon.
Or this one:
UnGraph
Often you see a graph, chart, picture or drawing and wish you could easily get hold of the X,Y data from which it was drawn. Now, you can scan such material with any scanner or photograph it with a digital camera and UnGraph will be able to give you the coordinates with a high degree of precision.

Uhmm, no ... (unless they dramatically redid the interface) ... but I don't really care as long as it does the job ... off to try it! Thanks Molly! – Rook – 2010-01-09T21:12:26.547
added a few more you to check :) – None – 2010-01-09T21:34:21.273
1Yes, yes, ok, ok ... I get the point ... I suck at searching ;) ... DigitizeIt it was I was originally searching for, but I think now I even like more some of other you've found. – Rook – 2010-01-09T21:35:34.017
1+A+1 <-- you deserve full points for this treasure (and believe it or not, these kind of apps can be a huge time saver (and I do mean HUUGE) – Rook – 2010-01-09T21:37:15.247
